With the advent of zenith camera, it became possible to improve the accuracy (up to 0,1″) and efficiency (no more than an hour) of measuring the plumb line deviation components at the point where the device is located in real-time mode. This enables measuring the components of the mentioned deviation at 4–12 or more points, depending on the season, during one observational night. Zenith camera is field-based, relocatable and can quantify the required components with any given discreteness, the process is fully automated. This makes the possibility of using the well-known method of astronomical leveling in a new way to define the height differences of the quasi-geoid. With a mistake in computing the deviation of a plumb line of 0,2″, the error in determining the elevation of the quasi-geoid heights is less than 1 mm at a kilometer distance between the points. This indicator is comparable with miscalculating of existing levels. In this case, there is no need for direct visibility between measurement points, computations can be performed between unrelated spots, and the distances between them can be kilometers or dozens of them. The authors present reviews of works on the use of zenith camera in creating quasi-geoid height models, develop the theory of astronomical leveling, consider its errors, and compare it with other leveling methods.

The possibility of studying morphometric parameters of the Earth’s topographic surface using the ArcMap and digital elevation model SRTM3 with a resolution of 90 m to determine neotectonic structures, as well as associated ore clusters and deposits was considered using the method offered by V. P. Filosofov. The authors describe the technology of creating base and vertex surfaces for thalwegs and watersheds of different orders, with the subsequent subtraction of the former from the latter within one order to determine the amount of erosion cut (relief energy). As the object of the study, the Dnieper-Donets aulacogen was chosen, starting west of Kharkov and stretching to the Caspian Sea, wide from Rostov-on-Don to Millerovo. It was noted that the higher the potential relief energy is, the more powerful surface processes will be manifested in the form of active destruction of previously buried (hidden) geological structures with valuable components, which are later to be distributed throughout the territory. This study is proposed to be used to predict and search for latent mineralization; it enables identifying the root source of demolition, rational arranging geological work, and thereby reduces their cost.

Thorough study of the equipment is essential before any measurements are made. Relative tidal gravimeters are complex technical devices; they enable measuring gravity time variations with high accuracy (1 μGal). The main source of systematic errors is their instrumental drift. Value and nonlinearity of the drift for each unit is individual. There are plenty of considering methods; they depend on material and technical opportunities. The simplest and less resource-consuming algorithm is to take the drift into account using the piecewise linear approximation technique. This research deals with assessing the accuracy of accounting the instrumental drift of the gPhoneX#117 (Micro-g LaCoste, USA) tidal gravimeter using the specified means. For this purpose, the drift was obtained through approximation by polynomials of the first and second degree was estimated in comparison with the results of reference (absolute) observations. It is concluded that the method of piecewise linear approximation can only be used for rejecting poor quality measurements. It is recommended to identify, control and accounting the instrumental drift by comparing measurements with the data of regular absolute monitoring.

At present, the use of digital technologies is becoming increasingly relevant in all fields of anthropogenic activity. In agriculture, an important area of digitalization is precision farming. In this case, the method of analyzing remote sensing data in geoinformation systems is of great importance; it enables identifying various parameters of agricultural crops (indices of vegetation, moisture availability, etc.) at processing. Therefore, it is important to develop a computer technology for manipulating the mentioned information and creating digital maps and models of the territory based on it. This requires high-quality work at the available satellite imagery materials. The author considers the course of determining the vegetation cover water indices in the ENVI software package using satellite images of the Landsat 7–9 survey systems. Based on the results of the calculation, digital 2D maps of the object under study were compiled, a GIS project (database) was developed, and a 3D elevation model was created. The obtained materials are intended for the analysis of natural and anthropogenic features, as well as for assessing the moisture content of the study object’s territory vegetation cover.

Taking the most developed part of the Baikal basin as example a digital cartographic reconstruction of the regional nature management of the early XX century is compiled; it enables establishing the physical and geographical characteristics of the territory economic use in the past. As a result of nature management objects retrospective layers vectorization and subsequent transformation of their shp files into the ArcGIS environment spatial object classes, two cartographic sets of such classes were formed. They characterize two types of regional nature use, traditional pastoral and invasive agricultural. As a result of layer-by-layer geoinformation modeling of cartographic sets on a modern topographic basis and a digital relief model, primary areas of settlement and economic use of the territory were established, and various mapping of spatial and temporal life support structures of nature management different types was performed. For operational digital visualization, a technological solution is proposed for storing and mapping sets of classes of spatial objects through arrangement of a file-based geodata of the ArcGIS information environment. Cartographic reconstructions of pastoral and agricultural nature management at the beginning of the XX century are presented, as well as its general cartographic reconstruction on landscape basis.

There is an extensive amount of research works in the field of land inventory. However, in modern scientific and technical literature, they do not deal with designing a multi-level information base for the inventory of agricultural land, a priority category of land. There is practically no detailed description of the database formation in existing papers. The aim of the work is consistent designing a bank of data for the agricultural land inventory. So, the authors discuss the procedure for carrying it out, provide an analysis of modern technologies in order to form semantic and graphical parts of the information base, and outline the features of its sequential design. The research methods of theoretical and empirical level were used. We have presented the automation for the process of entering data into the base using GIS technologies. As a result, the final outcome was obtained, a multi-level bank for land inventory. The approbation results of the proposed production are presented on the materials of the Pskov oblast.

The authors propose an algorithm for predictive monitoring of 3D-changes in the terrain relief due to the processes of slope erosion. The algorithm is based on the phenomenological law, from which it follows that the intensity of soil losses at the slope is proportional in magnitude and inverse in the direction of the declivity height gradient vector. In conjunction with the differential equation of mass balance, a mathematical model of the terrain relief change is built. The model enables calculating it at an arbitrary time according to its shape at the initial moment based on the solution of a standard mathematic boundary task. Comparing the results of solving such a problem with the data of cartographic monitoring makes it possible to establish a relationship between the slope erosion coefficient and the type of soil, vegetation cover, and meteorological conditions under which the studied area is located, and then predict changes in the terrain relief in the future.
